HELPS DISSOLVE STONES: Innovative urinary tract cat food helps dissolve pure struvite stones and helps prevent calcium oxalate stones

BLADDER HEALTH: RSS methodology for cat bladder health lowers the risk of crystal formation

S/O INDEX: The exclusive S/O Index creates an environment unfavorable to crystal formation in the bladder to support urinary health

HELPS PREVENT STONE REOCCURANCE: Specialized diet, with a reduced level of magnesium, helps prevent struvite stones from reoccurring

When your cat has urinary issues, easing their discomfort requires special care. But with the help of your veterinarian and Royal Canin, there’s not just hope—there can be a true difference.

This veterinary-exclusive morsels in gravy wet cat food was developed to nutritionally support your adult cat’s urinary tract and bladder health. It increases the amount of urine your cat produces to help dilute excess minerals that can cause crystals and stones. Relative Super Saturation (RSS) methodology is used to help lower ion concentration in urine, which contributes to stone formation. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. And this specialized nutrition, with a reduced level of magnesium, helps dissolve pure struvite stones and prevent struvite stones from forming. Lower urinary tract issues may be a recurring concern for some cats. Talk to your veterinarian about keeping your cat on this urinary cat food for long-term urinary support. And ask them about the right Royal Canin dry cat food and treats to complement your cat’s diet.

What happened?

I have been using this for my cat for years and recently bought a case that smelled AWFUL. The case after that was huge chunks and way too much liquid in it and she doesn't like it anymore. You are going to lose customers. Leave the product as it was. Don't try to fix what isn't broken. You had a good product and now it's terrible.

Great until Formula Changed

My cat has been on this food for the last 4 years. I love that this food has kept him healthy & without crystals. However, they recently changed the formula. Now I’m having trouble getting my cat to eat it, which is of great concern due to his health issues. It’s super watery & splashes everywhere when you open the can. The morsels are in basically water now instead of gravy. I’m not sure what or why they changed in the ingredients but I would love to know for the safety of my cat. Royal Canin, what did you change in this formula?? This food has gone up in price a lot & I would expect better quality.

Like so many people have said- this is the ONLY food they will eat! They will not touch the canned loaf style and they begrudgingly eat the dry SO. I really wish they made 6 oz cans… it would make my life a lot simpler! But this is the best.

Average Food

I don't know if the formula/ ingredients changed during the food shortage but my cats refuse to eat it now.

My cat’s favorite!

I’m so so sad that they don’t make this kind anymore, and so is my cat. This was her favorite and it stopped her stones from coming back! She’s picky so it took a little while to adjust to the paté. Would love if it could come back!

Please bring back!!!

Like so many of the other reviews have said, my cat will only eat this food! He needs to be on this diet and just meows in protest at any other kind, including the loaf. Please please please bring this back!!!

Picky old cat loves the gravy beans.

Our 14yo cat was prescribed this food almost 10yrs ago. He started with the loaf version but when we switched to this kind (we call this mini can version "beans" because of the texture) he never wanted loaf again. He wont eat the Calm or Moderate Calorie Urinary SO beans, but he will eat the non-rx Aging beans, Urinary beans, and now we've had him on the Renal beans (another rx. Not his rx but our vet approved while there aren't any other beans available). He's having a hard time with the inconsistency of his diet. We're forcing too many switches. I really hope the Urinary SO beans come back to regularly being in stock. Our old catman can't take so much diversity. And this is his true rx.

Please bring this back

My cat refuses to eat any other food and cries all day for this wet food. He hasn’t had it in a month, please please bring it back.

Picky Cat loves this

My cat is very picky and absolutely loves the morsels. He needs to be on a urinary diet for life and will not eat any other kind (including the loaf). Really hoping this is back in stock soon; I do not know what I will do long term.
